| 摘 要： | 无证书密码体制不仅有效地解决了基于身份密码系统中固有的密钥托管问题而且成功地避免了公钥证书的使用,近年来得到了广泛的应用。基于无证书密码系统,提出了一个新的无证书短签名方案,新方案构造简洁、高效,在签名验证阶段仅需2次对运算。方案在随机预言机模型下是可证明安全的,更适于在公开且低带宽的通信环境下应用。

| Abstract: | Recently,certificateless public key cryptography eliminated the use of certificates in certified public key cryptography and the key-escrow problem in identity based cryptography,which was applied widely.A new certificateless short signature scheme is proposed based on the certificateless cryptography.The new scheme is constructed compactly and efficiently,and signature verification requires only two pairing operation.The scheme is provable secure in the random oracle model.It is more suitable for public and low-bandwidth communication environment. |
